Text

Style long-form content without a class on every element: wrap it in .prose from @tailwindcss/typography, tuned to htmx-ui's tokens. Small helper classes cover single elements in UI chrome.

Prose#

Wrap plain HTML (an article, Markdown output, CMS content, a server-rendered fragment) in .prose. Every heading, paragraph, list, link, quote, table and code element inside is styled. No per-element classes.

Shipping hypermedia

Your server already renders HTML. htmx swaps it in; htmx-ui makes it look good.

Return a fragment from any endpoint, point hx-target at it, and you're done. See installation.

Plain HTML in, styled content out

.prose comes from @tailwindcss/typography, which htmx-ui/styles.css loads for you. Everything in its docs works: sizes (prose-sm, prose-lg), element modifiers (prose-a:text-primary, prose-headings:tracking-tight), and max-w-none to drop the default line-length limit.

What htmx-ui changes#

Colours come from the tokens: body and headings use --foreground, links --primary, rules and table borders --border, code blocks --code-background. Prose therefore follows custom themes and dark mode on its own. Don't add dark:prose-invert.
Inline code is a pill on a muted background instead of being wrapped in backticks.
Links get a soft underline that firms up on hover.
Headings get scroll-margin-top so #anchor links clear a sticky header.
Components placed inside prose with not-prose (alerts, code blocks, tables) get the same vertical spacing as paragraphs.

Components inside prose#

Prose styles every element inside it, which would also restyle a component's markup. Add not-prose to a component to keep its own styles. htmx-ui's Nunjucks macros (code, alert) already do. The flip side: .prose placed inside a not-prose element gets no styles at all, so don't nest them that way.

html

<article class="prose">
  <p>Before you deploy:</p>

  <div class="alert alert-warning not-prose" role="status">
    <div class="alert-title">Back up your database</div>
  </div>

  <p>Then run the migration.</p>
</article>

Sizes#

prose-sm: for sidebars, cards and dense UIs.

prose: the default, for articles and docs.

prose-lg: for landing-page copy.

html

<div class="prose prose-sm"><p><strong>prose-sm</strong>: for sidebars, cards and dense UIs.</p></div>
<div class="prose"><p><strong>prose</strong>: the default, for articles and docs.</p></div>
<div class="prose prose-lg"><p><strong>prose-lg</strong>: for landing-page copy.</p></div>

Customising further#

Tweak one block with element modifiers, or change prose everywhere by adding to the prose utility:

html

<article class="prose prose-headings:font-bold prose-a:no-underline">…</article>

src/styles.css

@utility prose {
  --tw-prose-bullets: var(--primary);

  & :where(h2):not(:where([class~="not-prose"] *)) {
    border-bottom: 1px solid var(--border);
    padding-bottom: 0.5rem;
  }
}

Single elements#

UI chrome (a page title, a hint under a form field) isn't long-form content. For one-off elements outside prose, use these helpers:

Manage your profile and preferences.

Danger zone

Deleting your account can't be undone.

Read the theming guide, run bun run dev, press Esc.

html

<p class="eyebrow">Settings</p>
<h1 class="h1">Account</h1>
<p class="lead">Manage your profile and preferences.</p>
<h3 class="h3">Danger zone</h3>
<p class="muted">Deleting your account can't be undone.</p>
<p>Read the <a class="link" href="/docs/theming">theming guide</a>, run <code class="code">bun run dev</code>, press <kbd class="kbd">Esc</kbd>.</p>

Which one?

More than a couple of text elements in a row is content: use .prose. A single label or title in a layout: use a helper.
